haawda [1] filed a deletion request for guipdftk [2]: Upstream supports Windows only and has version 0.49.1, Linux version (0.33) comes from a third party and seems to be abandoned. The sources do not build, and alternatives are available (pdfchain). [1] https://aur.archlinux.org/account/haawda/ [2] https://aur.archlinux.org/pkgbase/guipdftk/
